I was very pleased to see the texts re spraying, paints etc. I am fairly new to spraying my "Surfury" and it is taking some time.
I certainly agree with all the statements on preparation, for me this divides into 2 categories. 1. Boat surface preparation. 2 Paint consistency/temperature/spraying.
For 1 you cannot rush it, for as noted, gloss paint certainly shows up any imperfection so you must be dedicated to spend considerable time on this.
But 2. Right or wrong, after sealing and undercoating (plus the rub down) I chose to use Humbrol enamels. There followed many weeks of spraying after getting the mix right, correcting my spraying technique, inevitable rub downs etc. I came to the conclusion that many thin coats were the norm and cleaning of the spray gun (Badger) after every use was mandatory!
However, the best finish achieved was by spraying in a warm surrounding temperature. This was achieved in my garage with a small calor gas fire. I believe that this latter point is the most important of all.
When the painting is complete I will post a few pictures. Thanks to everyone for their excellent, informative replies.
